Toney, Pittsburgh, Pa., assignor to Pittsburgh Plate GlassCompany, a corporation of Pennsylvania Application June 28, 1934, SerialNo. 732,799 8 Claims. (01. 72.0-56.4)

The invention relates to store front construction employing strips orbars for the reception of the glass, and has for its principal objects;the provision of improved means for cushioning the glass on its rearface, particularly adapted for use with a sash bar of the relativelyrigid extruded type, in order to reduce the danger of cracking the glassdue to localized pressure; the provision of an improved setting blockconstruction which is not readily subject to displacement and which ispositively prevented from tilting when the weight of the plate isimposed thereon; and the provision of improved means for locking thecover strip in position, so that the danger of theft or unauthorizedentry through removal of the window is reduced. Certain embodiments ofthe invention are shown in the accompanying drawings, wherein:

Figure 1 is a perspective sectional view of the construction. Fig. 2 isa detail perspective view.

And Figs. 3 and 4 are sections taken at two different points along thelength of the sash bar and showing details of construction.

Referring to the drawings, I is the sash frame of the usual woodenconstruction; 2 is a metal sash bar which is seated in the sash frameand secured in position by means of the screws 3; 4 is one of a numberof clamping members moved into clamping engagement with the glass plateor sheet by means of the screws 5 (Fig. 2); 6 is the glass plate whichis clamped between the sash bar and the clamping members; I is the coverstrip or plate which lies over the clamping means and has releasableinterlocking engagement with the clamping members, as later described; 8is an ornamental paneling, preferably of carrara glass, lying in frontof the sash frame I and positioned with respect to such sash frame bymeans of the usual plastic cementing ma- 0 terial 9; I0 is one of thesetting blocks which support the weight of the glass sheet; and II isone of the locking bars for preventing the unauthorized removal of the.cover strip.

The sash bar 2 and the cover strip 1 are preferably extruded metalsections, while the clamping members 4 are formed of sheet metal bent ordrawn to the desired shape. The showing of Fig. 1 is that of theconstruction at the bottom of the window, but it will be understood thata similar construction is used at the sides. and top.

The sash bar 2 consists of a back strip l2 whose upper edge opposes therear faced the glass sheet 6, and a.base strip l3 which lies at rightangles to the back strip and extends forwardly to the front face of thepanel 8, as indicated in Fig. 1. The back strip is provided with adovetail groove carrying a spring cushioning member [4 of sheet .metalhaving two recurved lips 15 which engage the glass sheet. This gives ayielding engagement between the sash bar and 5 the glass, and isdesirable with a rigid extruding sash bar construction, in order toeliminate any danger of breakage due to localized pressure upon theglass. This strip has at intervals slots Hi to provide for drainage. 10

The sash bar is provided with a flange l1 in parallel with the basestrip I 3, thus giving a guide slot l8 which performs a double function,as later described. Seated upon the flange are the metal setting blocksIll which carry the 15 weight of the glass plate, two or more of suchblocks being employed suitably spaced along the sash bar, the numberdepending upon the size of the glass sheet. As indicated in Figs. 2 and3, these setting blocks are of L-shape in cross sec 0 tion with the longflange in parallel with the base strip of the sashbar andwith the shortflange extending vertically and engaging the base strip l3. The shortflange of the block is provided with a lip H! which projects into thegroove [8. 5 The upper face of the setting block is provided with acushioning pad 20 of leather or other similar yielding material to avoidinjury to the edge of the glass plate. These blocks give a very securesupport for the glass sheet due to the fact 30 that they are of metaland because of the engagement of the lip IS in the slot [8 whichprevents tilting of the block under the weight of the glass plate.

The clamping members 4 each comprise a ver- 35 tical clamping plate 2|having a flange 22 at its upper edge and a base plate 23 provided at itsouter edge with a recurved portion 24 which gives a locking recess forholding the cover strip 1 in position. The clamping member also has aflange 40 25 at the juncture of the plates 2| and 23, which flange fitsinto the groove l8 when the clamping member is moved to clampingposition by the screws 5. The groove thus acts as a guide for theclamping member and gives it a more secure sup- 45 port upon the sashbar. It also assists in holding the base plate of the clamping memberdown tightly against the base strip iii.

The cover strip is recurved to provide the groove 26 along its outeredge and such recurved portion is formedinto a rib or bead 21 so thatwhen the cover strip is pushed into position, it interlocks with therecurved portion 24 of the clamping member. At its inner edge, the coverstrip is provided with a flange 28 which fits beneath the 55 ingmaterial for flange 22 of the clamping plate when the cover strip ismoved to the position shown in the drawings, thus giving a securesupport for the edge of the cover strip.

When the parts are placed in assembled relation, as indicated in thedrawings, the cover strip is not subject to accidental displacement orremoval because of its interlocking engagement with the clampingmembers, as above described, but an unauthorized removal is possible forthe purpose of gaining entrance through the window, and in order toguard against this possibility, the positive locking construction shownin Fig. 4 is employed. This locking means comprises two bars ll, one ateach end of the sash bar, which are interlocked at their outer ends inthe groove 26 of the cover plate. To accomplish this result, the end ofthe bar is provided with the bulb 29 which is slipped into position fromthe end of the groove. The inner end of the bar is perforated andoverlies the flange ll of the sash bar. In order to lock the bar, a pin30 is employed, such pin extending through the flange at the upper edgeof the back strip, through the perforation in the locking bar and into arecess at the base of the flange IT. This locking means can be easilyapplied and released, and when once in position effectively guardsagainst the removal of the cover strip from the outer side of thewindow.
